RideTech Tru Turn System

[BonzoHansen]

This is basically what your guy at your booth told me last week when I asked if the TruTurn would work with the Global West arms I already have. Made total sense to me

Overall summary
These examples DO NOT tell us that other manufacturer’s components or systems are neccessarily inferior to the Tru Turn system. Instead they tell us that just because certain components will bolt up together, it does not necessarily mean that they will function properly together. Yes, your car will likely go down the road just fine for many years. No, a mismatched combination of parts will not offer “just as good” of handling performance as a complete system.
All the aftermarket examples showed a similar and significant improvement in camber gain. The differences seemed to be in the bumpsteer measurements. Bumpsteer is radically affected by the precise location of the various steering components. Different manufacturers will use slightly different locations for these components. When used as intended [as a complete system] they will achieve the intended goals. When combined with other [unknown] components, the end result may coincidently bolt together, but may not achieve the geometry that was originally intended.

I have ridetech drop spindles, wilwood sl6 front brakes, and dpe 18X8 fronts, wan tto go up to 18X10 with 275-295. Will the Set up work with my brakes?

Sure will. You will just need the kit w/o spindles. Will include steering arm, tie rod assemblies & drag link bracket.

Bret,

Excuse my lack of steering measurement expertise, but at what location fore/aft of the spindle is the toe in/out measured? Is that max. 0.070" toe change at the edge of the tire tread, or at the rim lip, or at some arbirary distance X from the ball joints' axis on the spindle?

Thanks!
Joe

Still having a hard time justifying this kit...

[marolf101x]

frojoe: We use this fancy measuring device to check bumpsteer (basically a "home made" version of the commercially available units out there):




When the tires are on the car and the car is on the ground you can check toe with these simple plates (a lot of racing companies sell these):



68camotion: If you want to fit a 10" wide wheel on the front of a first gen you only have a couple of choices 1-TruTurn; 2-new subframe. Since a new sub is many times the cost of the TruTurn it makes it much easier to justify.

Does this kit clear headers? Specifically small block chevy headers? If so what brands/kits are most likely to fit?

[darren@ridetech]

Had a customer that had clearance issues with his Hooker Super Comp headers on his small block. He ended up using Dynatech headers.

I am in the process of installing a TruTurn Steering System on my '69 Camaro .
It did not clear my Hooker Super Comp Headers on the passenger side . I swapped headers to a Summit Brand Header that was routed differently .
That wasn't a problem for me , because I had the wrong tube-size headers anyway and was looking to upgrade .
I think regular Hooker Headers will clear , but the Super Comps will not .

Here's where the inner tie rod end would interfere with the front lower header tube:


Here's a comparison pic : Notice how the front lower header tube on the Summit Header is further back.

lets say you install this system, by a quality set of upper and lower control arms, coil overs, we are talking around $3000 right? Well you are still stuck with the gear box and in ability to bolt on c5/c6 brakes?

StrongArms - upper and lower = $1,000
Tru Turn w/spindles = $1,000
Single adjustable coilovers = $650
Total = $2650

I would still recommend a good quick ration steering box, price likely around $400.

For brakes...look around on the Corvette forums for opinions on the oem Vette brakes. My personal experience in my C6 Z06 was that the brakes went away significantly after about 5-6 hard road course laps. My hotrods have Baer 13" rotors and 6 piston calipers on them...20 hard laps no fade at all. My 3650 lb. 66 Chevelle will stop from 60mph in 113 feet. An ABS equipped 3180 lb. C6 Z06 with PS2's takes about 118 ft. [This was all documented by Chevy Hi Performance Magazine last summer]. The point is, don't assume the C5/C6 stuff is necessarily the best thing out there. They would likely work great for autocross, but might fade on a heavy car on the road course.

right now im just trying to figure out what i want to do. Either spend $3000-$3500 to have a badass stock subframe or 7k for a really badass dse unit. Im thinking i would like to save my $3500 towards something else but i dont want to sacrifice my overall build

I love the idea behind the Tru Turn system but wish there was a second spindle option with no drop built into the spindle itself since my car already has the Hotchkis TVS. I see the Tru Turn kit being a great gap filler to something Hotchkis doesn't address, bump steer. In my mind the lowest cost way to keep both the Hotchkis front springs and have the Tru Turn is to use a 1.5 to 2 inch spring spacer (not ideal). Does anyone have an opinion on installing a Tru Turn using spring spacers? Thanks!

Any recommendations on the quick ratio box to use with the Tru Turn set up. Mine arrives Monday at Creative Rod and Kustom.

With a roughly 2:1 ratio on the Spring/Control Arm. You would only need a 1" spacer to maintain your current ride height.

[GeoffP]

That's not too bad - I'd consider doing it with just an inch spacer. I found that Global West makes aluminum coil spring spacers specifically for adjusting ride height. Thanks for the info.

[ScottT]

I have a stock front sub, speedtech upper and lowers, qa1 coil overs, ridetech spindles, and I am installing the rest of the tru turn kit. How wide of a tire can I use with the stock front sub, and also will it be helpful if i do the guldstrand mod or is the geometry better without?

I thought baer brakes are still made by pbr,does baer use stainless pistons like the ones you can buy to upgrade c5/c6 calipers?i would think pbr/the oe has more$ in research and development then baer or wilwood.not dogging your experience or anything just thinking .phil

[Chev67]

What headers will clear the Tru Turn with an LS install?
